COMBINATION' CABBONATOR AND DSPEINSXNG yBAM;

To allfwwm it may concern:

Be it known that l, ARCH B. GREEN, a citizen of the United States, and resident of San Francisco, county of San Francisco, and State of California, have invented a new and useful Combination Carbonator and Dispensing Barrel, ,of which the following is a specification.

The present invention relates to improvements in dispensing barrels and its object is to provide a combination carbonator and dispensing barrel, that is, to combine the carbonator directly with and to place it inside of the ldispensing barrel and to provide a faucet that controls both the dispen- 'sing apparatus and the carbonator and enables the operato-r to replenish the carbonator simultaneously with the withdrawal et carbonated water or independently of the' same. The faucet itself has been independ-4 ently protected in yU. S. Patent 1,383,100 and it is the'object of the present applicationto secure protection on the combination inwhich this faucet is to be used. v

rlhe preferred form of my invention is illustrated in the accompanying drawing in which Figure 1 represents a side view of my dispensing barrel, al portion of the latter being broken away to reveal the inside of the same; Figure 2 a horizontal cross-section through the same along line 2-2 of Figure 1; Figure 3 an enlarged detail view of the' carbonator proper enclosed in the barrel, Figure 4 an enlarged vertical crosssection through the valve, and Figure 5 a horizontal cross-section through the valve along line 5-5 of Figure 4.'

Referring to the draw-ings in detail, it will be noticed that the barrel (1) does not essentially di'er from the dispensin barrels now in common use in soft drin parlors and extensively used especially in connection with the retail sale of root beer. Since I developed my device principally as a root beer dispensing barrel, l shall, for the sake of simplicity, confine myself in my description and explanations to that expressich, although the apparatus can no doubt be used for many purposes of similar character. The barrel is preferably provided with double walls (2) and (3) and an insulating layer (4) between the same.

The carbonator (6) is di sed within the barrel and comprises a tu ularl body (7) specification of Letters' Patent.

having a lower chamber 8) servingas receptacle for the carbonated water, a rather thick layer (9) of loose material adapted to allow the water to percolate through the same resting on a perforated plate (11') secured within the tube and a mixing chamber (12) above the percolator. Water is admitted into this carbonator through the pipe (14), which may be connected to the city water supply and is led around the carbonator in numerous windings, whereby its surface is subjected to the influence of the ice (16) provided in the barrel. This pape ends into the top or mixing chamber (12) of the carbonator, but before arriving there is passed through the valve (18), as shown in Figure 4f, and illustrated in detail in U. S. Patent No. 1,383,100, so that the valve (18) controls the suppl of water yadmitted into the carbonator. t the end of the water pipe, within the mixing chamber, a line spray nozzle (20) is provided which separates the water into fine units so that it presents itself very much like a dense fog. ln this stage it is most receptive for the carboniol acid gas since it is cooled to a temperature of about 40 degrees and the air is forced out of it through the spraying process. Gas is admitted into the carbonator through the pipe (21), entering the same preferably through the filtering material. It then mixes with the water under the most favorable conditions, the water being cold and 'going through a carbonating process twice, first in the mixing chamber proper where the water entering in the form of a fine mist readily takes up the carbonio gas entering the chamber under pressure and secondly by percolating through the filtering material which is also saturated with the gas. Under these conditions carbonated water can be produced very cheaply and under rather low pressure. In a barrel that is now in operation my only power is the pressure in the city water line, which is rated at pounds; carbonio gas l introduce under a 25 pound pressure and obtain excellent results.

A pipe (22) ending into the faucet (18) is used for the withdrawal of the carbonated water and enters the carb'onator at (23), to be led inside the carbonato!" to the hottom of the same. receptacle (2t) -for syrup is provided in the upper portion of susl the barrel and syrup is withdrawn from the same through the pipe (26) by gravita tion. The latter pipe also leads into the faucet (18).

The construction of the faucet (18) is explained in detail in my former application and for the purposes of the present application it is only necessary to explain that the faucet is provided with one or more passages (31) adapted to bridge the break in the water inlet pipe (14) whereby it controls the water inlet, one or more ports (32) for the withdrawal of carbonated water adapted to connect with the pipe (22) and another port (33) controlling the syrup. The most preferred form of faucet for this urpose haring been illustrated in my 'ormer patent it is not deemed necessary to go into detail' on this subject, except that l might state that the 'faucet allows the operator to rell the carbonator independently or in connection with the withdrawal of carbonated water and also to draw on the ypure ice water, in that manner Aexercising a complete control over the carbonator as well as performing all the Jfunctions of a dispensing faucet, special provision being made tor allowing syrup to pass through t e faucet together with the carbonated water.

A gauge (36) is provided outside the barrel to indicate the level of the carbonated 'water in the carbonator, the lower end of the gauge communicating through the pipe (37) with the carbonated water in the carbonator, while the upper end ci the gauge communicates through the pipe (38) with the upper portion of the carbonator close to its top, so that this pipe can he simultaneousl used as an outlet for air gathering near tlie top of the carhonator, the pressure ci' which can be occasionally relieved by the use of the valve (89) at the top of the gauge. Pirovision is also made to allow the water athering at the bottomy oi the barrel to rain out ot the barrel through the pipe (41) which is protected troni the ice bythe il cap (42) and leads into the eneral drain pipe (t3), intoA which also ows any overdow water 'from the perforated glass supporting plate (at), as shown in the drawing.

rlhe carhonator is secured to the bottom of the barrel by means of the stud (to) projecting from the bottom of the carhonator and extending throughv the hole (t7) in the bottom et the harrel, a nut (t8) insuring misera tight engagement between the carhonator and the barrel.

ln operation the pipe (14) is connected with the city ywater supply or any other watersupply delivering water under a ressure of at least 25 pounds, and ice is p aced around the windings of the pipe.v The inlet (21) is connected to a supply of carbonio acid gas, the syrup tank filled, `and the device is ready to be used. The carbonator works automatically and, owing to the specii'ic construction of the valve, ice water is admitted to the carbonator 'any time carbonated water is withdrawn from the same. .lf the supply of carbonated water should get low, the operator may refill it by meansl of the same valve (18) without withdrawing any carbonated water. Thus my device clls the place of the common dispensing barrel as well as of the carloonator now commonly used as adseparate unit at a very sli ht increase of cost.
